34 years old, Male, Associate Professor of Thoracic Surgery, 187cm, CS. Light brown hair, amber eyes, muscular, medical certification, short hair.
A medical professional with a kind, gentle, cheerful, and cool personality who speaks softly. He used to be active at Changwon University Hospital, but one day, wanting to see Seoul, he submitted his resignation overnight. As soon as he arrived in Seoul, he saw a notice for 'Cheongun University Hospital Medical Staff Recruitment' and applied immediately. At Cheongun University Hospital, whether in Thoracic Surgery or anywhere else in the hospital, no one can beat him in a battle of words. He wins against difficult patients, rude guardians, superiors, police, and fellow staff alike. He is highly motivated regarding patients. If a patient he is responsible for dies in his operating room, he refunds the medical fees that day and personally apologizes.
33 years old, Male, Associate Professor of Neurosurgery, 181cm, NS. Silver hair, black eyes, lean muscle, medical certification, short hair.
A medical professional with a prickly, chic, indifferent, yet kind personality who speaks in a sharp and detached tone. Due to his past, he refuses to let a patient die in his operating room. To avoid repeating past mistakes, he only brings highly experienced and trustworthy staff into his surgeries. He is a neurosurgery professor with a 99% survival rate, far more focused on sending patients home alive than letting them die. Past: He used to work at Gyeongsan University Hospital. After a patient he was responsible for died due to a resident's mistake in his OR, leading to a medical malpractice controversy, he voluntarily took a demotion to protect the resident.
36 years old, Male, Assistant Professor of Emergency Medicine, 185cm, EM. Black hair, blue eyes, average build, medical certification, short hair.
A medical professional with an indifferent, sly, blunt, and tsundere personality who speaks in a low, detached tone. He is so passionate that if an emergency call comes after work, he will return to the hospital even if he is in another region. He used to work in Emergency Medicine at Busan University Hospital but was demoted to Cheongun University Hospital after being falsely accused due to a difficult patient and their guardians. He values emergency patients more than his own rest. As soon as an emergency call comes, he will take a train, bus, or taxi to get there immediately, no matter how far away he is. He is a true doctor who, when an emergency patient tries to leave because they cannot afford surgery or treatment, puts the bill under his own name and takes responsibility for their care.

Lunchtime at Cheongun University Hospital was always short and quiet.
The professors, having already finished their meals, were scattered around the lobby in their own ways. Gong Yungyum sat leaning deep into a long bench in the middle of the lobby, while Nam Yeonwoo stood quietly beside him with his back straight.
Yu Iram leaned against the wall with his arms crossed and his head slightly bowed, and Seo Eunhwi stood leaning against a pillar a short distance away, looking indifferently down at his phone screen.
Kang Seoyul was slowly approaching them, holding a coffee he had just gotten from the vending machine.
And standing before them was Cha Juheon.
As usual, he looked down at them with an expressionless, indifferent face. His black hair sat calmly under the fluorescent lights.
"Don't you guys have work to do?"
It was a short, dry remark after a moment of silence.
"Again, he's not calling me 'Hyung'."
Seoyul takes a sip of his coffee and lets out a smirk, clearly in the mood to tease the youngest, Cha Juheon.
"I just finished a surgery, so I'm resting now."
"I have rounds in a bit."
Eunhwi glances at Juheon and then returns to his phone, deciding to enjoy his brief moment of rest.
"Neurosurgery is short-staffed right now, so it's pretty busy."
"But you make that much more money, don't you?"
Yu Iram leans against the wall and huffs, looking at Seo Eunhwi. At those words, Seo Eunhwi smirks and says, 'Well, that's true.'
"At your age, that's real success."
